Various studies deal with a combination of proxies, which are neither easy to compare nor is their connection easy to explain, e.g., due to spatial patterns and time transgression. Within this study, the suitability of the lacustrine sediments from the Laguna Salada (Andalucía region, southern Spain) as a paleoclimate archive is investigated. The lake sediments were evaluated using a multi-proxy approach including sedimentological, mineralogical, geochemical and biological analyses. The sediments reflect the evolution of the lake from pre-Medieval times onwards and Characeae as well as Ostracod analyses give an indication of paleosalinity. Moreover does the geochemical composition provide profound information concerning changes of elemental and mineralogical composition. Nevertheless, a robust, high-resolution chronology could not be achieved owed to the scarcity of material available for radiocarbon dating and contamination problems. Furthermore, poor preservation of pollen restricted the reconstruction of vegetation history, which could have complemented important information concerning climatic changes and human activity. 2018-05-18T12:55:50+02:00 c.willmes@uni-koeln.de Loess and other Quaternary sediments in Germany http://crc806db.uni-koeln.de/dataset/show/loess-and-other-quaternary-sediments-in-germany1525423844/ 2018-05-04T08:50:44+02:00 janina.boesken@geo.rwth-aachen.de;stephan.poetter@geo.rwth-aachen.de Relating Norwegian palynological records and archaeological datasets http://crc806db.uni-koeln.de/dataset/show/relating-norwegian-palynological-records-and-archaeological-datasets1523871710/ In this contribution we present the first results of a project that aims to create detailed GIS-based paleoenvironmental information from a comprehensive data set of pollen core data from Norway. This comprehensive dataset is created by the Norwegian paleobotanist Helge Høeg during more than 30 years. The pollen data comes from more than 300 drill cores and the main part of them are collected as part of archaeological excavation projects in South-Eastern Norway. Until now this data was published mostly in textual form as tables or as figures (pollen diagrams). The digital pollen count data itself has never been published and has therefore not been available for quantitative analysis before. The study will use quantitative statistics and software tools like R and GIS are used to create a comprehensive paleoenvironmental data set of high temporal and spatial resolution for the last ~10.000 years of South-East Norway. This new paleoenvironmental data set of high temporal and spatial resolution, will help to better analyze and understand the Holocene history and archeology of Norway, by relating to archaeological spatial datasets from the Museum of Cultural History at the University of Oslo. This pilot study has a large potential for more advanced paleoenvironmental studies in Norway and neighbouring countries (especially for the Stone Age), and also for technical/theoretical refinement of GIS applications to archaeological metadata. 2018-04-16T09:41:50+02:00 c.willmes@uni-koeln.de Leptholithic technology as a cultural marker in early European Anatomically Modern Humans dispersal and its counterpart in Neanderthals: a further look to South-East Europe. http://crc806db.uni-koeln.de/dataset/show/leptholithic-technology-as-a-cultural-marker-in-early-european-anatomically-modern-human1523867079/ Poster presented in the framework of the European Geoscientists Union general meeting 2018. The poster highlights the lack of a comprehensive direct lithic assemblages comparison, crossing traditional EUP technocomplexes, in order to achieve a meaningful understanding of AMH dispersal in Europe. it presents a layout of the intended author´s PhD research, which will be focused on bladelet production. 2018-04-16T08:24:40+02:00 jgennai@uni-koeln.de Improved moist-convective rotating shallow water model and its application to instabilities of hurricane-like vortices http://crc806db.uni-koeln.de/dataset/show/improved-moistconvective-rotating-shallow-water-model-and-its-application-to-instabiliti1522834461/ We show how the two-layer moist-convective rotating shallow water model (mcRSW), which proved to be a simple and robust tool for studying effects of moist convection for large-scale atmospheric motions, can be improved. The improvement is achieved by including, in addition to the water vapour, precipitable water, and the effects of vaporisation, entrainment, and precipitation, rendering the model cloud-resolving. It is applied, as an illustration, to model the development of instabilities of tropical cyclone-like vortices. 2018-04-04T09:34:20+02:00 mrostam1@uni-koeln.de
